Adapt to take 2, or parent face with 1! This double kit is the second seat for your Phil & Teds Voyager buggy. Voyager buggy’s second seat is just as adaptable as the main seat! The double kit converts to lie flat mode, so 1 or 2 newborn babies can rest on & off the buggy. As your 2nd baby grows, the double kit converts back to an upright stroller seat. Plug and play your way by connecting the double kit to the front or the back – then you are up and away with 2 happy little riders!
